The majority of ATP molecules derived from the breakdown of carbohydrates are generated by (the):

1.   ?    anaerobic fermentation and glycolysis
2.   ?    fermentation and electron transport
3.   ?    glycolysis and substrate phosphorylation
4.   ?    Kreb's cycle and electron transport chain

In the electron transport chain, the final electron acceptor is

1.   ?    oxygen
2.   ?    water
3.   ?    cytochrome oxidase
4.   ?    hydrogen ion

An enzyme functions to increase the rate of a reaction by

1.   ?    increasing the concentration of the substance
2.   ?    decreasing the energy of activation
3.   ?    competing with the substrate
4.   ?    hydrolyzing the substrate

Fermentation:

1.   ?    requires oxygen
2.   ?    does not require oxygen
3.   ?    produces large amounts of energy
4.   ?    occurs only in bacteria

Glycolysis is most closely linked with what part of the cell?

1.   ?    nucleus
2.   ?    mitochondrion
3.   ?    cytoplasm
4.   ?    endoplasmic reticulum

One of the differences between aerobic and anaerobic respiration is that in anaerobic respiration

1.   ?    glucose is used in energy production
2.   ?    ethyl alcohol is a product
3.   ?    ATP is a product
4.   ?    carbon dioxide is a product

Muscle fatigue results from the accumulation of lactic acid in muscles because of

1.   ?    enzyme deficiency
2.   ?    oxygen deficiency
3.   ?    excess number of mitochondria in the cell
4.   ?    inability to metabolize glucose

Aerobic respiration involves all of the following except?
